The Radium Engineering Port Injection Kit (PIK) installs between the intake manifold and the cylinder head. It permits the use of port injectors for the additional fuel required for highly-modified B58TU engines. This does NOT replace the OEM direct injection system.

The fuel rail is CNC machined from extruded 6063 aluminum and laser etched for a high quality surface finish. Both end ports are machined with 8AN ORB (3/4-16 female) threads.
The injectors are mounted at a calculated angle to ensure proper spray into the center of the intake ports without sacrificing interference from surrounding components.
The PIK adapter plate can also be used as a simple intake manifold spacer without using the fuel rail. All that is required are 2AN ORB Plugs shown below.
Relocation hardware is provided to allow the OEM engine vanity cover to be reused.
4 included adapters install into the underside of the vanity engine cover and make up for the intake manifold shifting.

VEHICLE COMPATIBILITY

The fuel rail features 2 threaded ports that are tapped for 8AN ORB. What is ORB?

If building a custom fuel setup, appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.
